Product Information: The fan is the component that pushes fresh air in to the combustion chamber, allowing the gas to be burnt correctly. It also extracts the toxic gas after the combustion process is complete. The boiler has safety protocols in place to make sure no gas can be passed through to the main burner if the fan is not operational.
